Abstract
In this paper, a unified gradient-based treatment for optimizing certa in performance indices under the constraint of pole assignment is prov ided. By introducing a free optimization parameter and solving a speci al Sylvester matrix equation, compact gradient formulae are derived fo r general-purpose gradient descent numerical implementation. Special p roblems including robust stability pole assignment and H-2 sensitivity reduction are employed to illustrate the technique. In particular, co mparisons of different performance indices to maximize the complex sta bility radius are made.
